Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a grass removal device with an anti-blocking function. Background Art

[0002] With the development of society, agricultural mechanization is becoming more and more popular. When harvesting crops such as wheat and rice, combine harvesters are basically used. In order to improve the utilization rate of wheat and rice straw and avoid the fire hazard caused by straw burning, combine harvesters are equipped with straw crushing devices. They can crush the straw in the combine harvester and then throw it into the farmland through the grass discharge port to return the straw to the field.

[0003] After searching, patent CN206821285U discloses a "combine harvester grass cutting and discharge device". Although the grass cutting and discharge device can be turned upside down through the connecting frame, the inside of the threshing chamber can be repaired and other related operations can be carried out from the grass discharge port without disassembly. Of course, the utility model can also disassemble the connecting frame and the grass cutting and discharge device together. However, only a single set of cutting knives is provided in the device, which makes it easy for straw to be blocked in the grass discharge port, greatly reducing the spreading efficiency. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a grass discharge device with an anti-blocking function, so as to solve the problem that only a single set of cutting knives is provided, which causes straw to be easily blocked in the grass discharge port and greatly reduces the throwing efficiency.

[0005] In order to solve the above technical problems, the technical solution of the utility model is as follows: a grass discharge device with an anti-blocking function, comprising a grass discharge bin, a mounting plate is fixedly connected to the rear side of the grass discharge bin, a motor is arranged on the left side of the grass discharge bin, a rotating shaft is arranged at the output end of the motor, a first gear is fixedly connected to the other end of the rotating shaft, a second gear is meshed with the outside of the first gear, the number of the second gears is two groups, and both of them are meshed with the first gear;

[0006] The side wall of the grass discharge bin is provided with a bearing, the inner ring of the bearing is fixedly connected with a rotating rod, the rotating rod is fixedly connected with a rotating roller, the rotating roller is arranged in the grass discharge bin, and the rotating roller is fixedly connected with a cutting knife.

[0007] Preferably, arc-shaped plates are symmetrically arranged on both sides of the grass discharge bin, one side of the arc-shaped plate is fixedly connected to a clamping ring, the inside of the clamping ring is movably connected to the clamping ring, the right side of the clamping ring is fixedly connected to a short rod, one end of the short rod extends out of the clamping ring and is fixedly connected to a threaded sleeve.

[0008] Preferably, a baffle is provided on the front side of the grass discharge bin, threaded columns are fixedly connected to both sides of the baffle, and the threaded sleeve is movably connected to the baffle via the threaded columns.

[0009] Preferably, the roller rotates in the grass discharge bin through a rotating rod, a second gear and the first gear.

[0010] The above scheme is adopted: the two sets of rollers can be rotated by means of the motor, the rotating shaft, the first gear, the second gear, the rotating rod and other components, so that the straw blocked in the grass discharge port can be crushed, effectively avoiding the problem of reduced spreading efficiency due to blockage.

[0011] Preferably, the internal thread of the threaded sleeve is matched with the external thread of the threaded column.

[0012] Preferably, the threaded sleeve is movably connected to the arc plate through a short rod, a clamping ring and a clamping ring.

[0013] The above solution is adopted: the position of the baffle can be accurately adjusted through components such as clamping rings, clamping rings, short rods, threaded sleeves, threaded columns, etc., so that the size of the grass discharge opening can be changed according to usage requirements, and the applicability of the machine in different working environments can also be increased.

[0014] By adopting the above technical solution, by turning on the motor, the motor drives the rotating shaft and the first gear to rotate, and with the cooperation of the second gear, the rotating rod rotates accordingly, thereby rotating the roller. During the rotation process, the roller will drive the cutting knife to cut the straw blocking the grass discharge port, thereby realizing the cleaning of the straw. The two sets of inclined rollers not only increase the effective cutting area, but also ensure the efficiency and quality of the operation. In addition, the addition of bearings improves the rotation smoothness of the rollers, further ensuring the efficient operation of the machine. The two sets of rollers can be rotated by means of components such as the motor, the rotating shaft, the first gear, the second gear, and the rotating rod, thereby crushing the straw blocking the grass discharge port, effectively avoiding the problem of reduced spreading efficiency due to blockage.

[0015] By adopting the above technical solution, by rotating the threaded sleeve, the retaining ring moves to one side under the cooperation of its internal thread and the external thread of the threaded column, releasing the limit on the thread, and sliding the baffle along the grass discharge bin. When the threaded sleeve reaches the position of another group of threaded columns, the threaded sleeve is rotated in the opposite direction, and the threaded sleeve is sleeved on the outside of the threaded column to limit the baffle, thereby completing the adjustment of the size of the grass discharge port. The position of the baffle can be accurately adjusted through components such as the retaining ring, retaining ring, short rod, threaded sleeve, and threaded column, so that the size of the grass discharge port can be changed according to usage requirements, and the applicability of the machine in different operating environments can also be increased.
